long story short me and my husband were separated when he passed, our children were 6 & 9 at the time. Even though we were still married I was suppose to get his burial flag at his funeral, but at his mother’s request she wanted it until the girls were old enough or she passed. I reluctantly granted her wishes even though now I know it was the worst decision ever. Now my children are 21 & 25 and his half sister took the belongings after the mother passed and has decided she wants to keep the flag. There was no will, and we actually had to wait until the mothers bf passed before obtaining anything from another family member. My children are devistated. Is there anything we can do?
